evolve: add evolve info to cmdutil.afterresolvedstates
Adding evolve info to cmdutil.afterresolvedstate will improve the ui when we run
into merge conflicts while evolving. Once we resolve all the conflicts using `hg
resolve`, this will show a message saying "continue: hg evolve --continue".
Other extensions like rebase and shelve also use it and it's very helpful.
Testing the handling of phases for `hg evolve` command
$ cat >> $HGRCPATH <<EOF
> [phases]
> publish = False
> [alias]
> glog = log -G --template='{rev} - {node|short} {desc} ({phase})\n'
> [extensions]
> EOF
$ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH
Testing when there are no conflicts during evolve
$ hg init noconflict
$ cd noconflict
$ echo a>a
$ hg ci -Aqm a
$ echo b>b
$ hg ci -Aqm b
$ echo c>c
$ hg ci -Aqsm c
